The CMS silicon strip tracker operated stably through Runs 1 and 2, with a readout saturation issue understood and fixed in 2016, and radiation damage models projecting survival to 500 inverse femtobarns.

abstract
During autumn 2008, the Silicon Strip Tracker was operated with the full CMS experiment in a comprehensive test, in the presence of the 3.8 T magnetic field produced by the CMS superconducting solenoid. Cosmic ray muons were detected in the muon chambers and used to trigger the readout of all CMS sub-detectors. About 15 million events with a muon in the tracker were collected. The efficiency of hit and track reconstruction were measured to be higher than 99% and consistent with expectations from Monte Carlo simulation. This article details the commissioning and performance of the Silicon Strip Tracker with cosmic ray muons.

Operation and performance of the CMS silicon strip tracker with proton-proton collisions at the CERN LHC
The CMS silicon strip tracker operated stably through Runs 1 and 2, with a readout saturation issue understood and fixed in 2016, and radiation damage models projecting survival to 500 inverse femtobarns.
